SPECIFICATION forming part of Letters Patent No. 309,318, dated December16, 188%.

Application filed May 26, 1884.

ger-handle, which are adjustable to varying sizes and tapers ofauger-shanks, and which embody improved means for operating the same,whereby the clamps are made to grip the auger-shank with great force.

In the drawings forming part of this specification, Figure l is a planview of the under side of an augerhandle; and Fig. 2 is a similar viewthereof, showing the centrallylocated clamp-ease in section. Fig. is aside elevation, partly in sect-ion, and said three figures illustrate anauger-handle constructed according to my invention. Fig. at is a view ofone of the clamps. v

In the drawings, b is the clampcase, to one end of which is fixed one ofthe ordinary wooden handles, a, and the other one is secured to theclamp-collar c, which screws into one end of said case b. The inner endof the clamp-collar c is made with an interior inclined clamp-seat,z.The clamp-case, as well as the collar 0 and the clamps to, are ofsuitable metallic construction. The case I) is provided with an annularshoulder, (1, around its interior, and has the clamp-pin c passingtransversely through it, and adapted to be firmly secured thereto. Theclamps 'v o are pro vided each with a shank-groove, as shown, to furnisha suitable receiving-socket for the tapering shank of the anger in, andone end of each clamp is perforated to form a pin-hole, a', throughwhich the pin 0 passes when the clamps are in operative position in thecase b, and on which the clamps have a certain degree of vibratorymotion and an endwise movement,

and hence said pinholes are made larger than the pin 0. The ends of theclamps n adjoining the shoulder d are bevelethas also are their ends adjoiuing the inner end of the collar 6, and the lastnamed ends of theclamps are adapted to have a bearing on the abovementioned seatz in thecollar when the latter is forced against them, as hereinafter set forth.By reason of the size of the hole :0, as compared. with that of theclamp-pin c, as above described, the clamps are permitted to rock on thepin to adjust themselves to anger-shanks of greater or less taper, andtherefore they adapt themselves to large and small shanks. In Fig. 3only the shank part of an anger, w, is shown.

In operating my improvements the handle a,which has the collar e securedto it, is turned to unscrew the latter to draw it away from the ends ofthe clamps o and let them open. The shank of the anger is then insertedbetween the clamps, and said collar-handle is turned, forcing collar 0against the ends of the clamps, and thereby they are first moved againstthe shoulder (1, whereby their ends adjoining the latter are forcedtogether, and simultaneously therewith the ends of the clamps in thecollar are likewise forced toward each other, and, consequently, theshank of the anger is tightly secured between the clamps, and the latteradjust themselves to the taper and size of the shank. Turning collar 0 alittle away from the ends of the clamps releases the augershank.

IVhat I claim as my invention is- In an auger-handle, the clamp-case b,having shoulder d therein, the clamps o 7), having their ends beveled,the pin a, passing through said case and the ends of the clamps, and thescrewcollar e, adaptedto be forced against one end of the latter,combined and operating substantially as set forth.-
